What kind of change does this PR introduce?
Feature (implements a requested enhancement)
What is the current behavior?
When test coverage is displayed in the editor, coverage indicators (covered/uncovered lines) are shown in the line number gutter and optionally inline, but there is no coverage visualization in the minimap. Users who want to quickly scan for coverage gaps in a file must scroll through the entire document.
Closes #258961
What is the new behavior?
Coverage indicators now appear in the minimap gutter, showing covered regions in green and uncovered regions in red. This allows users to see coverage gaps at a glance without scrolling.
Changes:
testing.coveredMinimapBackgroundandtesting.uncoveredMinimapBackgroundregistered intheme.ts, with defaults matching the existing gutter coverage colors (green for covered, red for uncovered)testing.coverageMinimapEnabled(boolean, defaulttrue) inconfiguration.tsto let users toggle minimap coverage indicators independentlycodeCoverageDecorations.tsnow includeminimap: { color, position: MinimapPosition.Gutter }when the setting is enabled. The observable config value is read reactively so toggling the setting updates the minimap immediately.Additional context
The implementation follows the same pattern used by the SCM quick diff decorator (
quickDiffDecorator.ts), which adds minimap indicators for added/modified/deleted lines usingthemeColorFromId()andMinimapPosition.Gutter.
